Title: Image transmission system
Inventor: TATSUTA MASAYUKI
IPC: H04N19/00
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To send simultaneously a moving image and a still image with high image quality through the use of a transmission line at a comparatively low speed by dividing the still image into lots of images, inserting each of the divided still images into a moving image data stream and transmitting the moving image and the high image quality still image in a form of the data stream. SOLUTION: In the case of synthesizing moving image data and still image data, a part of data configuring a high image quality still image is segmented and partial data B1, B2,... of the high image quality still image are inserted one by one to moving image data A1, A2,... of a moving image data stream to form one data stream. Then the transmission is controlled so that the partial data B1, B2,... do not give effect on transmission of the moving image. Thus, moving image data roughly indicating a motion and high image quality still image data capable of indicating detailed parts for each prescribed period are transmitted as one data stream.

Title: Digital information reproducing device
Inventor: KAMIKADO TOSHIKAZU
IPC: G11B7/0033
Filed: 1987-04-10
Abstract: PURPOSE:To reduce the mechanical processing time of a digital information reproducing device, by demodulating information recorded in a prescribed format after reproducing the information from the front and rear sections and rearranging the demodulated information when necessary. CONSTITUTION:An address mark detecting circuit 9 detects a special pattern which does not fit a demodulation law from reproduced read data passed through an amplifier 8 for waveform shaping and supplies a demodulation starting signal to a demodulator means 10. NRZ signals demodulated by the means 10 are written in a storing means 13 through a serial-parallel converting means 11 and rearranging means 12. On the other hand, a discrimination signal in the demodulated data from the means 10 is detected by an ID detecting means 14 and it is discriminated whether a format is reproduced from the right side or left side in accordance with the discrimination signal on an MSB side or that on an LSB side. When it is discriminated that the format is reproduced from the left side by a data reading controlling means 15, the parallel output of the means 11 is rearranged by the means 12. Therefore, data reading is executed during the course of rewinding and, as a result, mechanical processing time can be reduced.

Title: Detecting system of ground velocity of radar
Inventor: ROBAATO JIYON HOTSUFUA
IPC: G01S13/58
Filed: 1984-05-04
Abstract: A vehicle carries a radar transmitter (12) and receiver (14) which provides a Doppler signal representing vehicle ground speed. The Doppler signal is processed by a Schmitt trigger (18) and a flip-flop (20) to generate a symmetrical square wave whose instantaneous pulse-width is the reciprocal of the Doppler frequency. A microprocessor is interrupted by edges of the square wave and processes the pulse-width to produce a symmetrical output square wave (23). The processing steps comprise:
 (1) Input pulse widths exceeding a threshold value set by a timer are ignored
 (2) When the input pulse width INVAL is within 121_2% of the output pulse width OUTVAL the latter is updated in accordance with a weighted average, OUTVAL = (15 OUTVAL + INVAL)/16
 (3) When the input pulse width INVAL deviates more than 121_2% from the output pulse width OUTVAL no updating occurs unless this situation has persisted for 8 or more input pulses, whereupon more abrupt updating occurs in accordance with a second weighted average
 OUTVAL = (3 OUTVAL + INVAL)/4
 where INVAL is the average INVAL over 8 input pulses when the second weighted average is first used but is the latest input width when the situation has persisted for more than 8 input pulses.

IPC: G01M11/00
Filed: 1986-04-18
Abstract: PURPOSE:To accurately and speedily measure and inspect characteristics of a cylindrical lens from a closed curve drawn by projecting a track of a projection light beam of an optical fiber on a vertical plane through the cylindrical lens by letting an optical fiber make one turn. CONSTITUTION:The cylindrical lens 1 to be inspected is inserted loosely into a holder 53 and a ferrule 22 is allowed to make one turn, thereby projecting the track of the light beam from the optical fiber 2 on a display 7 through the lens 1. When the axial refractive index distribution of the lens 1 is correct, its projection track is circular as shown by a solid line and if there is abnormality, a closed curve deviating from the solid line as shown by a dotted line is drawn. If an end surface 11 of the lens 1 slants on a plane, the curve becomes more elliptic and elliptic as the inclination is more and more and if both end surfaces 11 of the lens 1 slant individually, two superposed circumscribed ellipses are formed. Further, the distance between the lens 1 and the slanting end surface 21 of the optical fiber 2 is varied thereby enabling measurement and inspection of practically essential characteristics such as the distortion of an image due to the unevenness of the concentric particular part of the end surface 11 and the effective internal diameter of the lens 1 from the mutual similarity of the locus.
